Annual home maintenance budget calculator.
Explore a range of annual savings targets from a home value and percentages you choose. This is a savings plan, not a prediction of repair bills or a contractor quote.
Annual and monthly targets
| Scenario | Annual | Monthly |
|---|---|---|
| Lower | ||
| Your target | ||
| Upper |
Existing planned spending and existing reserves are two different comparisons; do not add the two gaps together. The reserve gap assumes no withdrawals or interest and is not a promise that this year's repairs will match the target.
How this budget works
For each scenario, annual target = your home value × your chosen percentage ÷ 100. Monthly target = annual target ÷ 12. The planned-spending difference is max(0, target − planned annual spending). The first-year reserve gap is max(0, target − current reserve), divided by 12 for an illustrative monthly contribution. Values are calculated before rounding to the nearest cent for display.
Worked example: For a hypothetical $350,000 home, a 1% lower scenario is $3,500 per year (about $291.67/month), a 2% target is $7,000 ($583.33/month), and a 4% upper scenario is $14,000 ($1,166.67/month). If $1,000 is already reserved, the gap to a $7,000 reserve is $6,000, or $500/month over twelve months before any withdrawals.
What this estimate does not know
Home value is not the same as replacement cost. This tool does not estimate local labor or materials, inspect your house, distinguish planned maintenance from urgent repairs, account for interest or inflation, or determine whether you can afford a target. Get written local estimates for major work and use your own maintenance history to revise the percentages. Keep a separate plan for other household emergencies.
